본 고안은 자동차의 주차브레이크용 해제경고장치에 관한 것으로, 특히 운전자의 부주의로 인하여 주차브레이크를 작동시켜 놓은 상태에서 자동차를 주행하는 것을 경고하기 위한 해제경고장치에 관한 것이다.The present invention relates to a release warning device for a parking brake of a vehicle, and more particularly to a release warning device for warning the driving of the vehicle in a state in which the parking brake is operated due to the carelessness of the driver.

일반적으로 주차브레이크는 자동차의 주차시의 상태를 유지하기 위하여 자동차를 기계적으로 제동시키는 장치로, 자동차의 추진축에 설치된 브레이크드럼을 제동하는 센터브레이크식과 뒷바퀴를 제동하는 뒷바퀴브레이크식이 있으며 이들은 모두 브레이크라이닝의 마찰로 제동되도록 구성되어 있다.In general, the parking brake is a device for mechanically braking the car to maintain the parking state. There are a center brake type for braking the brake drum installed on the propulsion shaft of the car and a rear wheel brake type for braking the rear wheel. It is configured to be brake by friction.

이러한 주차브레이크를 운전자의 부주의로 인하여 작동시켜 놓은 상태로 자동차를 주행시키게 되면, 브레이크라이닝이 마모되거나 엔진에 과부하를 주어 브레이크와 엔진의 수명을 단축시키게 된다.If the vehicle is driven while the parking brake is inadvertently operated, the brake lining may be worn or the engine may be overloaded to shorten the life of the brake and the engine.

따라서 종래에는 경고램프를 계기판의 일측에 구비시켜 주차브레이크가 해제되지 않았음을 운전자에게 경고해 준다. 즉 주차브레이크레버에 연동되는 주차브레이크스위치가 온된 상태에서 시동을 걸면, 배터리전원이 경고램프를 구동하여 운전자에게 주차브레이크가 잠겨있음을 경고하게 되는 것이다.Therefore, in the related art, a warning lamp is provided on one side of the dashboard to warn the driver that the parking brake is not released. That is, when the parking brake switch interlocked with the parking brake lever is turned on, the battery power drives the warning lamp to warn the driver that the parking brake is locked.

그러나 이와 같이 주차브레이크가 작동된 상태에서 시동을 걸 경우 경고램프가 점등되는 것은 운전자가 이를 시각적으로 용이하게 인식할 수 없기 때문에 경고램프가 점등된 상태, 즉 주차브레이크가 잠긴 상태에서 주행하는 경우가 종종 발생된다. 그러므로 브레이크라이닝이 조기 마모되어 교환시기가 짧아지고, 엔진에 과부하를 주게 되어 엔진의 수명을 단축시키는 문제점이 있었다.However, if the warning lamp is turned on when the vehicle is started with the parking brake activated, the driver may not be able to easily recognize it. Therefore, the driver may be driven with the warning lamp turned on, that is, the parking brake is locked. Often occurs. Therefore, the brake lining is worn out prematurely, the replacement time is shortened, overloading the engine has a problem of shortening the life of the engine.

본 고안은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 엔진의 시동을 걸면 주차브레이크의 해제 안내음으로, 주행을 시작하면 경고음으로 운전자에게 주차브레이크 해제의 주의를 줄 수 있는 자동차의 경고장치를 제공하기 위한 것이다.The present invention is to solve the problems as described above, to provide a warning device of the vehicle that can give a warning of the parking brake release to the driver as a warning sound of the parking brake when the engine is started, when the driving starts.
